Kolars have less recoil because most of them weigh 9 pounds or more.
I do believe that long forcing cones, somewhat bigger bores and long choke taper do contribute to better patterns, but each of these things only provide a tiny improvement. Lots of excellent competitors have their barrels "Eysterized" no matter whose gun they are shooting. I consider my Perazzi with 0.740 bores, long cones and factory original 6.5" fixed chokes to be the ultimate in barrel performance. For serious competition it gets fed B&P ammo - this way I have zero excuses and all the confidence in the world in my equipment.

Jeff
